, This made much more efficient use of its fuel than the older Newcomen engine. Initially the business was based at the Soho Manufactory near Boulton's Soho House on the southern edge of the then-rural parish of Handsworth. However most of the components for their engines were made by others, for example the cylinders by John Wilkinson.
In 1795, they began to make steam engines themselves at their Soho Foundry in Smethwick, near Birmingham, England. Between 1775 and 1800, Boulton and Watt produced 496 engines.BOOK, Briggs, Asa, The Age of Improvement, 1994, Longman, 26, The partnership was passed to two of their sons in 1800. William Murdoch was made a partner of the firm in 1810, where he remained until his retirement 20 years later at the age of 76. The firm lasted over 120 years, albeit renamed "James Watt & Co." in 1849, and was still making steam engines in 1895, when it was sold to W & T Avery Ltd.For ten years their banker in London was Charlotte Matthews after her husband died in 1792. A woman banker was unusual but she became a close confidante, holidaying with Boulton, and she lent them enormous sums to fund their endeavours. When she died aged 43 in 1802 her business was run by the Boulton and Watt families.{{Citation |title=The Oxford Dictionary of National Biography |date=2004-09-23 |url=http://www.oxforddnb.com/view/article/70352 |work=The Oxford Dictionary of National Biography |pages=ref:odnb/70352 |editor-last=Matthew |editor-first=H.

Among the names which were employed there in the eighteenth century were James Law, Peter Ewart, William Brunton, Isaac Perrins, William Murdoch, and John Southern.JOURNAL, Transactions of the Newcomen Society, Steam and the engineering community in the eighteenth century, Buchanan, R.

The firm left an extremely detailed archive of its activities, which was given to the city of Birmingham in 1911 and is kept at the Library of Birmingham. An additional archive was donated to the Boulton and Watt collection in 2015 including a thesis.Dr John Richardson (Accession number 2015/049) P.h.D.thesis, University of Reading, 1989.
